Abstract

Dengue Haemorrhagic fever (DHF) is one of fearsome diseases in society. Incidence of the disease isincreasing. Dengue fever is caused by dengue virus and transmitted by Aedes aegypti mosquito vector.Various chemical controls have been conducted to prevent the spread of the disease, but active contents ofthe chemical controlling substances are suspected causing many negative effect, in environment, such asvector resistance, death of non target living creatures, and environmental contamination.This researchobjective was to find an alternative solution in order to control the dengue vector by using entomopathogenicfungi as biological control agent. This research was conducted by isolation and identification of fungiinfecting mosquito larvae. Macroscopic observation revealed that one of the nine isolation products wasLagenidium giganteum. The effectiveness test in laboratory showed the zoospore LD50 to Ae.aegypti larvaeof instar 2nd was 2,35 x 106 zoospore/ml, while the LD95 value was 1,35 x 107 zoospore/ml. The oosporeeffectiveness test showed LD50 was 6,7 x 102 oospore/ml and LD95 was 1,94 x 103 oospore/ml. Using LPCBdye and blue tolouidin 2,5%, the infection mechanism of L.giganteum fungi in Ae.aegypti mosquito larvawas detected. The research is concluded that the entomophatogen fungi L. giganteum was very prospectiveto be used as a biological control agent against vector of DHF.

Abstract

A study was carried out to find out an alternative method of producing antitetanus antibody (IgY) in chicken and to evaluate its activity at different levels of pH, temperatures and proteolytic enzymes. Antitetanus IgY was produced by immunization of chickens with tetanus toxoid, three times weekly at gradual doses of 100, 200, and 300 Lf, respectively. Serum samples were collected 4 weeks following the last immunization. IgY was purified by ammonium sulfat precipitation and gel filtration chromatography (Sephadex G. 120).The purified IgY was then treated at different levels of temperatures and pH as well as proteolytic enzymes. Commercial antitetanus IgG was used as control. The activities of treated IgY and IgG were tested by enzyme linked immunosorbent assay (ELISA). IgY and IgG activities were significantly reduced at 80ºC and completely destroyed at 90ºC. Treatment with pepsin significantly reduced IgY and IgG whereas trypsin slightly reduced IgY activities and has no effect on IgG activities. IgY and IgG activities were reduced significantly at pH < 3 and and only sightly reduced at pH>10. It is evident that heating at >90oC, pH at <3 and treatment with pepsin significantly reduced IgY activities and it appears that IgG was more resistent to the efect of temperatures, pH and proteolytic enzymes

Abstract

Importation of feeder cattle from farms constantly using antibiotics in feed could result in the occurrenceof antibiotic resistant bacteria. A study was therefore conducted to investigate the possible use antibioticsand the antibiotic resistance of commensal Salmonella sppagainst several antibiotics. Salmonella spp.bacteria (n=50)were isolated from 100 samples of feeder cattlesfaeces. Total of 50 Salmonella spp. isolateswere subjected for Salmonella spp. examination and the isolated Salmonella spp. was tested for theantibiotic resistance using 10 antibiotics (ampicillin, cephalotin, erythromycin, tetracycline, streptomycin,chloramphenicol, trimethoprim, trimethoprim-sulfamethoxazole, nalidixic acid, and enrofloxacin) usingdisk diffusion method on Muller-Hinton agar following Clinical and Laboratory Standards Institute (CLSI)guidelines for interpretation. The isolated Salmonella showed resistance towards erythromycin 98%,ampicillin 34%, streptomycin 22%, nalidixic acid 8%, cephalotin 6%, tetracycline 4%, and chloramphenicol2%. There was no resistance against enrofloxacin, trimethoprim, and trimethoprim-sulfamethoxazole. Salmonella spp. bacteria derived from imported feeder cattle which have been resistant to antibiotics arepotential for spreading the antibiotic resistant bacteria to other susceptible animals. Such bacteria canalsotransfer the antibiotic resistant gene to other bacteria in Indonesia which ould be a potential threatfor public and animal healths.

Abstract

This study was carried out to determine the use of bird flu polyvalent vaccines containing two or threeor more virus isolates representating of circulating viruses in the region. Three seed isolates of avianinfluenza H5N1 virus were used in this experiment. The isolates were Chicken/Denpasar/Unud-01/2004,Chicken/Klungkung/Unud-12/2006, and Chicken/Jembrana/Unud-17/2006. The seeds were inactivatedusing 0.01% formaldehide than mixed (AI3G) alumunium hidroxide adjuvant and then injectedintramuscularly to Isa Brown layer chicken at 3 weeks of age and repeated at the age of 5 weeks. The doseof each seed virus was 27 HA units. Sera were collected at one and two weeks after the second vaccination.The result showed that the arithmetic meant titer (AMT) of sera that tested with homologous isolate washigher than the test using a heterologous isolates, in the standard haemaglutination inhibition (HI) assay.The mixed AI3G vaccine produced a uniform AMT against the constituent isolates, while vaccines withindividual isolate yielded a lower and more variation in AMT. Further experiments using a commercialhomologous H5N1 and heterologous H5N2 commercial vaccines has resulted AMT that 1-4 log lower thanAI3G vaccine. It is concluded that polyvalent vaccine with field seed isolates is recommended to be appliedin the poultry farm in Indonesia.

Abstract

Consensus sequence of hemagglutinin (HA) gene of avian influenza viruses of H5N1 subtype isolatedfrom fowl in Indonesia – hereafter named as H5N1_Indonesia – is compared with that of H5N2 and H5N9viruses. Sequence information were downloaded from the public database GeneBank. The genetic distancesand nucleotide as well as its deduced amino-acid sequence alignment were analysed. At nucleotide level,genetic distances of HA between H5N1_Indonesia to H5N2 and H5N9 are 16.2% and 9.6%, respectively.At amino-acid level, the distances are 9.7% and 6.8%. The genetic distances of HA1 fragments are 19.0%(H5N1_Indonesia – H5N2) and 10.9% (H5N1_Indonesia – H5N9). At amino-acid, level the genetic distancesof HA1 are 13.1% (H5N1_Indonesia-H5N2) and 8.8% (H5N1_Indonesia – H5N9). All three subtypes havedifferent glycosilation motive and variation of amino-acid sequence of four antigenic sites. The consequenceof those facts is discussed.

Abstract

Gen mobilized colistin resistance (mcr) merupakan gen resistan kolistin sulfat yang bisa dipindahkan melalui materi genetik bergerak misalnya plasmid. Tujuan dari penelitian ini adalah mengetahui jenis plasmid gen mcr-1 yang berhasil dipindahkan dari satu isolat Escherichia coli resistan kolistin ke Salmonella Enteritidis ATCC 13076 (dua isolat), dan satu isolat E. coli O157:H7 resistan kolistin positif gen mcr-1. Sekuensing gen mcr-1 kemudian dianalisis di unit Biotek Balai Besar Pengujian Mutu dan Sertifikasi Obat Hewan dengan menggunakan basic local alignment search tools (BLAST) dan software MEGA7. Hasil sekuensing gen mcr-1 dengan panjang nukleotida 309 memiliki homologi tinggi dengan data referen dari Genbank pada gen mcr-1 yang terdapat dalam plasmid. Hasil sekuensing DNA gen mcr-1 sampel lebih cenderung termasuk pada tipe plasmid IncI2 atau IncHI2. Hal ini menunjukkan bahwa resistansi kolistin merupakan ancaman yang nyata karena gen resistan mcr-1 yang ada di Indonesia benar berada di plasmid sehingga mudah disebarkan ke bakteri lain. Kata kunci: mcr-1, plasmid, resistansi ABSTRACT The mobilized colistin resistance (mcr) gene is a colistin sulfate resistance gene that can be transferred through mobile genetic material such as plasmids. The purpose of this study was to determine the type of plasmid mcr-1 gene that was successfully transferred from an isolate of colistin-resistant Escherichia coli to Salmonella Enteritidis ATCC 13076 (two isolates), and one colistin-resistant E. coli O157: H7 that positive mcr-1 gene. The sequencing of the mcr-1 gene was then analyzed in the Biotek unit at National Veterinary Drug Assay Laboratory using basic local alignment search tools (BLAST) and MEGA7 software. The sequencing of the mcr-1 gene with nucleotide length 309 has a high homology with the reference data from Genbank on the mcr-1 gene contained in the plasmid. DNA sequencing of mcr-1 gene samples is more likely to belong to the IncI2 or IncHI2 plasmid types. This shows that colistine resistance is a real threat because the mcr-1 resistance gene in Indonesia is actually in the plasmid so it is easily spread to other bacteria.

Abstract

The variation of response on the production of specific IgY to tetanus toxoid among chickenin serum and egg yolk was observed in this study. Chicken showed relatively late response inproducing specific IgY in serum, around 59 days were needed to have a positive precipitationreaction of complex IgY-tetanus toxoid in the immunodiffusion test (agar gel precipitation test/AGPT). The presence of IgY in egg yolk could be detected one week after positive reations inserum was observed. The positive reaction in AGPT mostly related with the positive reaction inELISA, eventhough the variation of titer values were observed among chicken sera and egg yolk.This response variation might be related with the different of physiological status of the chicken.

Abstract

Immunoglobulin Y (IgY) in yolk has been shown in several studies to prevent both bacterial and viralinfections. This research was conducted to find evidence that IgY specific against avian influenza virus(AIV) of H5N1 subtype can be produced in a large quantity in egg yolk. Laying hens were vaccinated withAI killed-vaccine (IPB-Shigeta). The IgY was purified using affinity chromatograpy technique, and anti-H5activity was measured using a standard haemaglutination inhibition (HI) and agar gel immunodifusion.The concentration of IgY was calculated, and the protein pattern was detected using polyacrilamid gel(AGID) electrophoresis (PAGE). Anti H5 antibody as high as 27 – 29 HI units was detected and produce aspecific line of precipitation in AGID. The concentration of IgY was 7.89 mg/ml. Purified specific IgY consistof 6 main protein bands with molecular weights ranging from 35 to 225 kD. These proteins were sensitiveto heat treatment (75oC for 30 minutes), to acid condition (pH2) as well as the pepsin and trypsin. Theseresults indicated the possibility of using specific IgY for passive immunisation to prevent AIV infection oras immunotherapeutic applications for AI treatment in humans.
